Abstract
β-quartz glass-ceramics, the composition of which is most particularly optimized, with reference to the refining of their precursor glasses, with reference to good resistance to devitrification of said precursor glasses and with reference to their resistance to temperature ageing, articles comprising such glass-ceramics, lithium alumino-silicate glasses, which are precursors of such glass-ceramics, as well as methods for preparing such glass-ceramics and articles.
